It seemed like true love when Emily Maynard and Jef Holm got engaged on the season finale of The Bachelorette in July. But have they called it quits?

Multiple reports claim the reality lovebirds have split up.

A source tells PEOPLE the couple have drastically cut back on the amount of time they've been spending together recently. On Sunday, they were spotted at an event together, but, says the source, have otherwise barely seen each other.

Fresh off the set of Dancing with the Stars , Marini challenged fellow all-stars contestant Palin to a dance off, but she refused.

"No! He'll beat me! Gilles has the best moves!" she said.

Bachelorette winner Holm was more than up for a challenge! He took on both DWTS' Karina Smirnoff and Pretty Little Liars star Ashley Benson.

Although he attended the event without fiancé Emily Maynard, he assured everyone their relationship remains strong despite breakup rumors.

"Jef said he and Emily are extremely happy and the rumors are false," an onlooker said.

A pregnant Madison also got in on the fun and was overheard talking about possible baby names.

"The names she and boyfriend Pasquale Rotella are debating are definitely unconventional," a source says. "But they're straying away from anything trendy or common most people would choose."

Kym Johnson is a two-timeDancing with the Starschampion, taking the coveted mirror ball trophy in season 9 with Donny Osmond and in season 12 with Hines Ward. The Australia native will now be blogging for PEOPLE.com about competing with Joey Fatone in the all-star season.

Poor Joey.

He was so nervous about the elimination last week because I made him freak out. I felt bad about that. He just knew that I was nervous all day and he said, "Kym, I think we'll be fine," and I said, "Joey, we're fourth from the bottom. We could be gone."

The pair sat side by side for the big show and snapped photos after with all-star contestants and pro dancers, including Kirstie Alley and Kym Johnson.

Arie, who lost out to Jef in the finale, told PEOPLE at the post-premiere party at Mixology 101 at The Grove that he came into town to support fellow racecar driver and defending Dancing champ Hélio Castroneves.

One day after denying tabloid reports claiming Bachelorette star Emily Maynard had betrayed fiancé Jef Holm, the couple were hurt – but not surprised – to discover the allegations were made by Holm's own brother, Mike Holm.

"My family all says they are shocked, and obviously I'm shocked," Jef tells PEOPLE exclusively about Mike, who vacationed with the Holms family, Maynard and Maynard's 7-year-old daughter Ricki in Myrtle Beach, S.C., last weekend. "But if everybody knew the history he had with our family, no one would be surprised."

"It's one hundred percent not true," Maynard tells PEOPLE exclusively of the cheating accusations.

According to reports, the couple had a blowout fight while vacationing with Holm's family and Maynard's 7-year-old daughter Ricki in Myrtle Beach, S.C., last weekend.

"It's funny to me," Holm tells PEOPLE. "We were in a gated community in a private home with just my brothers and sisters. It's just bogus a 'source' would [say] we were fighting. None of that is true."
